Pedestrian and vehicle shunting method and system for straight lane and pedestrian crossing

Abstract

The invention provides a pedestrian and vehicle shunting method and system for a straight lane and a pedestrian crossing. The pedestrian and vehicle shunting method comprises the steps of 1) setting atime threshold by a server; 2) forming each corresponding lane fence area on the zebra crossing of the pedestrian crosswalk; 3) enabling a high-definition camera to collect video images of each lanefence area at the same time and transmits the video images to the server; 4) enabling the server to perform decoding and image identification analysis processing according to the video images of all the lane fence areas to form traffic light control information; 5) switching the colors and the durations of the corresponding straight lane traffic lights; 6) processing violation information; and (7)repeating the steps (3) to (6) to realize continuous operation. Only a lane where pedestrians enter and an adjacent lane are controlled, and a method of forcibly prohibiting the pedestrians from continuously occupying a road to pass is combined, so that the pressure of passing of motor vehicles on a straight lane and pedestrians on the pedestrian crosswalk can be effectively relieved, and the traffic safety is improved; the method and the system are widely suitable for intersection traffic control.

Description

technical field [0001] The invention relates to traffic control equipment, in particular to a method and system for separating pedestrians and vehicles from a straight lane and a crosswalk. Background technique [0002] In the urban traffic system, there are a large number of pedestrian crossings on the straight multi-lane, and there are inherent contradictions and conflicts between the passing needs of people and vehicles. In order to solve such contradictions, the current method of setting manual traffic lights at pedestrian crossings, that is State The pedestrian light is red and the vehicle light is green. When pedestrians want to cross the road, manual control is applied to switch the vehicle light to red and the pedestrian light to green. The state of the light is maintained for a fixed time and then automatically switches back to the default state; Although the method guarantees the passing order of pedestrians and vehicles, it has the following two defects: ① In toda...

[0002] In the urban traffic system, there are a large number of pedestrian crossings on the straight multi-lane, and there are inherent contradictions and conflicts between the passing needs of people and vehicles. State The pedestrian light is red and the vehicle light is green. When pedestrians want to cross the road, manual control is applied to switch the vehicle light to red and the pedestrian light to green. The state of the light is maintained for a fixed time and then automatically switches back to the default state; Although the method guarantees the passing order of pedestrians and vehicles, it has the following two defects: ① In today’s increasingly urban traffic pressure, this method has increasingly obvious shortcomings in the efficiency of road vehicle traffic, especially when the number of lanes is large. On the straight lane, the speed of pedestrians crossing the road is limited, so that as long as a small number of pedestrians cross the road, the traffic of all lanes in both directions will be completely suspended. Vehicles still need to wait for a period of time before they can resume traffic, especially in the case of a long straight lane with many pedestrian crossings, which is very likely to cause congestion, and the traffic efficiency of road vehicles is seriously reduced, further increasing traffic pressure; ② Not To fully realize the traffic principle of motor vehicles giving way to pedestrians, a single traffic light does not give drivers enough reminders, resulting in motor vehicles passing the crosswalk too fast, and because of the lack of recognition methods and compulsory punishment methods similar to running red lights at intersections, There are great hidden dangers in traffic safety at pedestrian crossings
